Apple patent may hint at sapphire touchscreens

A newly published patent application further hints at the possibility of sapphire displays in Apple products. The application for “oleophobic coating on sapphire” reveals a component that would feature a surface coating and transition layer on top of a sapphire glass base layer, which may be “a window for a portable electronic device.”

A described method would allow fingerprint-repelling oleophobic coating to be used on top of the sapphire glass. It’s been reported that Apple’s new Arizona sapphire plant has the capacity for mass production, with some speculating new iPhone displays could be made of sapphire.[via AppleInsider]
